Metadata: 2003 Scottish Natural Heritage (SNH) Sound of Arisaig Site Condition Monitoring survey
Abstract:
The purpose of the current study was to initiate site condition monitoring (SCM) of the inshore sublittoral sediment habitats of the cSAC. This was done to establish a baseline biological dataset that would facilitate the assessment of the condition of the inshore sublittoral sediment habitats in the future and to allow a judgement to be formed on the current condition of these habitats. The approach taken to achieve these aims was to perform an extensive dropdown video survey of the biotopes (habitats and their associated species) of the cSAC, concentrating on the shallow inshore sediments. Characterisation of the subsurface fauna and sediment composition of the main sediment biotopes was performed by means of grab sampling. Detailed surveying of the sea bed and subsurface communities at selected maerl sites was carried out using diving techniques.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The investigation was divided into three stages: 1) Dropdown Video: Knowledge of the distribution, diversity and extent of biotopes was gained by performing a stratified random sampling drop-down video survey, supplemented by a limited amount of focussed sampling. To promote adequate coverage of the different regions within the cSAC, the survey area between the 0m and 20m contours was split up into 20 strata. The area of each of these strata was measured within ArcView and a number of video samples allocated to each stratum in proportion to its size. The positions of sample stations within each stratum was determined by employing random numbers to generate a large list of potential positions which fell within the northern, southern, eastern and western bounds of the stratum. 150 stratified random sampling stations were selected using this method. At each station the video was deployed briefly from a drifting vessel, noting the times, depths and precise positions at the start and end of the drift. The runs averaged 4 minutes duration and 50m in length. In addition to the 150 stratified random sample sites, a farther 53 drop-down video sites were worked to provide coverage of the deeper areas, to fill in any perceived geographical gaps in the random samples and to position sites in the vicinity of locations previously surveyed by others. This fieldwork was carried out by SNH from the RIB Aphrodite, survey dates 05/07/2003 - 13/07/2003. 2) Grab Survey: Following categorisation of sample stations on the basis of biotope, sample stations representative of the different sedimentary biotopes were selected for analysis of the infauna and sediment composition by grab sampling at 20 stations. At each station a single 0.1m2 van Veen grab sample was collected using the vessel RV Serpula. A subsample of c.150ml sediment was taken from the surface of the grab contents for particle size analysis and the remaining material sieved on a 1mm mesh screen, the sievings being retained in borax-buffered 5% formalin. 3) Maerl Survey: Five maerl sites were selected for detailed examination of the infauna and epibiota along a 25m transect. A band 2m either side of the tape was surveyed by two divers, one on each side, who noted the presence, and where possible, estimates of the abundance of conspicuous biota, collecting material which needed to be identified in the laboratory. Representative samples of the algal community were also taken as well as samples of stones and shells for study of their epibiota in the laboratory. To supplement the real-time visual records and collections, the transect band was videoed using a hand-held digital video camera (Sony DCR-TRV900 in an Amphibico Navigator 900 housing) and at some sites still photographs taken of the maerl and associated community using a digital stills camera. The epibiota was surveyed using MNCR Phase II methods and 5 replicate cores, 10.3cm diameter corer to a depth of 20cm, were taken for infaunal analysis, and an additional 20cm sediment core of 5cm diameter was taken for grain size analysis. The areal extent of these maerl beds beyond the 25m transect was also assessed by performing drop-down video surveys at stations along lines radiating out from the station marker. |
